Changing the processor unit configuration

Learn how to display data and change the state for the processor unit (node).

About this task

You can change the state of the processor unit (node) by using the Advanced System Management Interface (ASMI).

To perform this operation, you must have one of the following authority levels:
  • Administrator
  • Authorized service provider
Note: This task is only supported on multiple node systems.

To view or change the processor unit (node) configuration, complete the following steps:

Procedure

  1. On the ASMI Welcome pane, specify your user ID and password, and click Log In.
  2. In the navigation area, expand System Configuration and Hardware Deconfiguration.
  3. Select Processor Unit Deconfiguration.
  4. In the content pane, select a node from the list of nodes.
  5. Click Continue to change the state of processor unit to configured or deconfigured, if it is not already deconfigured by the system.
    Note: The state of the processor unit can be changed only if the system is powered off. At run time, you can view, but cannot change the state of each processor. If the deconfiguration policy function is disabled, the state of the processor unit cannot be changed.
  6. Click Submit. A report page displays whether the state of the processor unit is changed.
